8. K120M CHARACTERISTICS
LED - DL3
The LED, besides indicating that the power supply is connected, also signals errors with a series of
pre-defined flashes:
steady light:
normal operation;
1 flash:
buffer battery voltage lower than 17,3 V DC;
Check the mains power supply, charge the battery, replace the battery;
2 flashes:
phototest error;
Disable phototest (dip-switch 6 OFF), check operation and connection of photocells;
3 flashes:
power failure;
Check the thermal-magnetic circuit breaker (upstream from system), check the fuses;
4 flashes:
max current limit exceeded;
Gearmotor has exceeded absorption limits, check for obstacles across the path of the gate, check the current
absorption of the motor when loadless and under load;
5 flashes:
absence of encoder signal;
Check wiring, check encoder through TEST-ENCODER (optional), verify that the motor turns freely if powered
directly by the battery, check fuse F2;
6 flashes:
presence of obstacle after 5 failed attempts to close;
Make sure there are no obstacles across the path of the gate and that it slides smoothly;
7 flashes:
no memorization procedure has been executed;
Execute memorization procedure.
8 flashes:
no motor signal.
check wiring, check that the motor rotates freely when powered directly by battery, check fuse F2.
Multiple errors are signalled by a 2-second pause between signals.
If the encoder is activated 5 consecutive times during the same closing manoeuvre (obstacle detec-
tion), the control unit opens completely indicating the error with the provided series of
next manoeuvre, the control unit will stop flashing and will switch to slow-down mode as it searches
for the closing travel limit.
If the photocells are activated 5 consecutive times during the same closing manoeuvre (obstacle detec-
tion), the control unit opens completely and stops without flashing.
vre, you need a new command.
